Outlook Express Identity start problems

[dusaig10]

I have problems with my Outlook Express.
Description of the problem:
I use XP with service pack 1 already added on instalation CD.
I added multiple Identities in my Outlook Express V 6.00.2800.1123
In Manage Identities section I set, that when I start my Outlook express, that it starts Main Identity. But this never happen.
If I use some other Identity beside Main Identity and then Shut down my windows XP professional, next time when I start Windows and then Outlook Express, it shows same Identity as before when I shut down Windows. So it not show Main Identity (which is set to start), but some other, which I used last time.

I don't know what I'm doing wrong.
My lap top computer have same settings as this Stationary computer, but on lap top all is working ok. On Stationary computer I'm having this kind of problems described in upper lines.

Any info on this problem will be much appreciated.

Thanks.

Best regards.
